Mar 14	comment	Discretization of Inhomogeneous Dirichlet Boundary Conditions for 2D Poisson's Equations That's what I thought! But the notes I have say the mass matrix, $A$, should be a size $25\times25$ matrix, but only consisting of 5-point stencil, not any of the values you have in orange/beige. Hence my confusion.

Mar 14	comment	Discretization of Inhomogeneous Dirichlet Boundary Conditions for 2D Poisson's Equations BTW, what did you use to create the diagrams?
Mar 14	comment	What was the first bit of mathematics that made you realize that math is beautiful? (For children's book) Is there some sort of repository of these mental math tricks? I'd love to see more of this stuff

Mar 11	comment	Uniformly Most Powerful Test and Rejection Region of Poisson Distribution This question seems more suitable for Cross-Validated (you might have better luck there). Just an FYI.
Mar 10	comment	Further clarification needed on proof invovling generating functions and partitions (or alternative proof) How is one supposed to realize that it is to make sense for $n \leq 2^m$? Its sort of misleading o.w. since the dots indicate it goes on forever.
